A comparative study of the voice-related quality of life among Egyptian elderly with and without voice complaints

Abstract

Abstract Background This study focuses on the self-perception of the voice in the elderly as assessed by the Voice-Related Quality of Life (V-RQOL) questionnaire. This work aimed to compare differences in the voice-related quality of life outcomes between (1) elderly with and without voice disorders, (2) female and male elderly with voice disorders, and (3) different types of voice disorders, and to explore the correlation between the V-RQOL and perceptual analysis done by the clinician. Forty-three dysphonic and 44 non-dysphonic elderly filled out the Voice-Related Quality of Life (V-RQOL) protocol that analyzes the impact of dysphonia on life quality. Vocal perceptual assessment of each subject with dysphonia was made by three voice therapists, followed by a flexible nasofibrolaryngoscope. Results A significant statistical difference was found between the means of total V-RQOL scores and its subdomains for each group (dysphonic and non-dysphonic). No significant differences were found between male and female elderly with dysphonia. The statistical analysis showed a significant correlation with the vocal assessment made by the clinicians and the V-RQOL self-assessment made by the subjects. Conclusions This study provides valuable information regarding the risk factors that contribute to vocal quality in the elderly population. Our results revealed that different types of voice disorders are common among the elderly population with significant negative effects on quality of life. It was observed that the poorest score on the V-RQOL was for functional voice disorders, followed by neoplastic lesions, whereas MAPLs had the best score on the V-RQOL.
